Order ID

Overview

As per Resolution 777, Orders shall be referred to using the specified format including the Airline Designator, Accounting Code (if available) and an 8 alpha-numeric value which uniquely identifies the Order within that Airline.

Within E&SD, all Orders shall return a correctly formatted Order ID and all requests for Orders shall use the Order ID. An Order ID is composed of 3 elements and consists of a concatenation of Airline Designator (2 or 3 character alpha-numeric), Airline Accounting Code (3 character alpha-numeric) and an Airline Reference (8 character alpha-numeric). Airlines without an assigned accounting code shall use ‘XXX’ in place of an accounting code. Detailed technical specifications for an Order ID are defined in IATA Resolution 777. For the transition phase, OrderRetrieve can be used to request an Order using a Booking Reference, however from that point on, the Order shall be referred to using the Order ID. Additionally, for the transition phase, underlying Booking References may be advised within the context of an Order.

Airline returning an Order without a Booking Reference.

Regardless of the underlying Order Management system, an Airline may return an Order ID when constructing an Order.

Using an Order ID is considered best practice within the Enhanced and Simplified Distribution messages.

Airline returning an Order which has an underlying PNR (for the transition phase)

An Airline may be mimicking a true Order Management System while still using PNR’s in the background. The Airline may still return the Booking Reference in the context of the Order for downstream processes.

Note in the below, the booking reference may simply be: HFUSBN.

For Airlines who have not migrated to an Order ID, and to allow for a consistent standard, the Airline may construct the Order ID using existing Booking References.
